The metal heating tube is usually installed with a heating wire in a metal tube, and then a high thermal conductivity insulating material such as magnesium oxide powder is poured into the heating tube, and the heating wire is encapsulated in the middle of the metal tube so that the heating wire does not directly contact the tube wall of the metal heating tube. For example, in the hot fast structure in the prior art, the heating wire will generate light radiation during the heating process of power on. Because the metal heating tube is filled with magnesium oxide powder, the light radiation cannot directly act on the medium to be heated, and this part of the light radiation heat is directly lost; for another example, when the existing heating tube heats the medium to be heated, because the heating tube does not have a light-heat conversion structure, when heating the medium to be heated, the light energy (light-heat radiation) emitted by the heating tube does not pass through the medium to be heated or penetrate the medium to be heated and is directly lost. It can be seen that the existing metal heating tubes or heating tubes have the defect of low heat conversion efficiency. Utility Model Content

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of some utility models, "plurality" means two or more, unless otherwise clearly and specifically defined.
[0027] This embodiment relates to a heating component, such as Figure 1-5 As shown, it includes: a heating tube 1 and a light-to-heat conversion structure 2.
[0028] The photothermal conversion structure 2 is sleeved outside the heating tube 1, and a heating chamber 201 is provided between the photothermal conversion structure 2 and the heating tube 1. The photothermal conversion structure 2 includes: a fixing seat 21 and a plurality of photothermal conversion sheets 22. The fixing seat 21 is fixed to the end of the heating tube 1. The end of the photothermal conversion sheet 22 is fixedly connected to the fixing seat 21. The plurality of photothermal conversion sheets 22 are spaced apart in the circumferential direction with the heating tube 1 as the center, and a gap 203 is provided between two adjacent photothermal conversion sheets 22, and the gap 203 is used to connect the heating chamber 201 with the outside. The inner and outer walls of the photothermal conversion sheet 22 are both black. The setting of the photothermal conversion structure 2 fully absorbs the light energy emitted by the heating tube 1 and converts the light energy into heat energy. Since the photothermal conversion plate 22 is made of metal, such as aluminum or copper and other metals with good thermal conductivity, and since the thermal conductivity of metal is better than that of liquid and gas, it can improve the heating efficiency and speed of the heating component for liquid and gas photothermal conversion, accelerate the temperature increase in the heating chamber 201, and realize the improvement of the electrothermal conversion efficiency of the heating tube 1.
[0029] It should be noted that the black color of the inner wall and the outer wall of the photothermal conversion sheet 22 is formed by a black oxide layer, such as a black electroplated oxide layer or a black chemical oxide layer. In other embodiments, the black color of the inner wall and the outer wall of the photothermal conversion sheet 22 is a black treatment layer 222, and the black treatment layer 222 is formed by a black coating or an oxidized black layer, such as a high-temperature resistant black paint coating, but not limited to black paint. The medium to be heated can be water or oil or other liquids. When the medium to be heated is water and the heating component is working, since the heating tube 1 is placed in the heating chamber 201 surrounded by multiple photothermal conversion sheets 22, the medium to be heated can The heat emitted by the heating tube 1 directly heats the medium to be heated in the heating chamber 201. The light energy penetrating the medium to be heated irradiates the photothermal conversion sheet 22 and is absorbed by the photothermal conversion sheet 22. Since the thermal conductivity of metal is better than that of liquid and gas, the photothermal conversion sheet 22 heats up faster than water. Since the temperature of the photothermal conversion sheet 22 is higher than that of water, the water in contact with the photothermal conversion sheet 22 is further heated, and the temperature rise in the heating chamber 201 is accelerated. Therefore, the heating efficiency and speed of the photothermal conversion of the liquid and gas by the heating component can be improved, and the electric heat conversion efficiency of the heating tube 1 can be improved. In other embodiments, the medium to be heated can be air.
[0030] In some embodiments, the photothermal conversion sheet 22 is a rectangular sheet, and multiple photothermal conversion sheets 22 are stacked in sequence on both sides. Figure 7 As shown, the extension line L1 of the length direction of the inner wall of the photothermal conversion sheet 22 intersects with the outer surface of the heating tube 1, and the angle between the tangent line L2 tangent to the outer surface of the heating tube 1 and the extension line L1 of the length direction of the photothermal conversion sheet 22 is greater than 0° and less than 90°, that is, the photothermal conversion sheet 22 is inclined.
[0031] It should be noted that after the light energy emitted by the heating tube 1 is irradiated to the inner wall of the photothermal conversion sheet 22, the thermal conversion sheet 22 converts the light energy into thermal energy to increase the temperature of the thermal conversion sheet 22. The part of the light energy that is not completely absorbed by the photothermal conversion sheet 22 is reflected by the inner wall of the photothermal conversion sheet 22 to the outer wall of the adjacent photothermal conversion sheet 22 to realize the re-conversion of light energy into thermal energy, so that the thermal conversion structure 2 can fully convert light energy into thermal energy, thereby accelerating the heating speed of the medium to be heated in contact with the thermal conversion structure 2.
[0032] In some embodiments, the photothermal conversion sheet 22 is an arc-shaped sheet, and the inner side surface of each photothermal conversion sheet 22 is coaxially arranged with the heating tube 1, and absorbs the light energy irradiated to the photothermal conversion sheet 22 to realize the conversion of light energy into heat energy, and the unabsorbed light energy is reflected back into the heating chamber 201.

The length of the plug-in portion 221 is less than the length of the photothermal conversion sheet 22, and the plug-in portion 221 is interference-fitted with the first plug-in grooves 202, so that the photothermal conversion sheet 22 is fixed on the heating tube 1 through the fixing seat 21.

The first plug-in slot 202 is penetrated on the first fixing ring 213, and the first fixing ring 213 is located in the fixing shell 212. In this embodiment, the fixing head 211 can be made of materials such as metal or ceramic, and the fixing head 211 is fixed to the outer surface of the heating tube 1 by interference fit or by bonding. The shell can be a metal product, and the shell and the fixing head 211 are fixed by screws or bonding or threads or interference fit. The outer surface of the shell is provided with a threaded structure, so that the heating component of the present application can be installed on an external heating device, such as a water heater. In this embodiment, the fixing head 211 is in a conical shape, so that the fixing head 211 and the fixing housing 212 can be installed, and the fixing head 211 and the fixing housing 212 have an interference fit. The first fixing ring 213 is welded or screwed to the fixing head 211. Furthermore, the first fixing ring 213 is black near the light-heat conversion sheet 22, and converts the light energy on the fixing seat 21 into heat energy, and prevents the unabsorbed light energy from returning to the heating chamber 201.
[0035] Preferably, in order to make the light-to-heat conversion sheet 22 more stably installed on the heating tube 1, as Figure 4 , 5 As shown, both ends of the photothermal conversion sheet 22 are provided with plug-in parts 221, and the heating component further includes a second fixing ring 3, on which a plurality of second plug-in slots 301 are provided, which are plugged one by one with the first plug-in slots 202, and the plug-in parts 221 at both ends of the photothermal conversion sheet 22 are respectively plugged with the first plug-in slots 202 and the second plug-in slots 301.

[0036] Furthermore, in order to make the light-to-heat conversion structure 2 more stable and reduce the displacement or deformation of two adjacent light-to-heat conversion sheets 22 due to external forces, as shown in FIG.
